/ 2' BY 24mm 0 WWW United States Patent 3,023,768 WATER PIPE DRAINEdvard Niemi, Veterans Hospital, American Lake, Wash. Filed Sept. 24,1958, Ser. No. 763,122 3 Claims. (Cl. 137-290) The present inventiongenerally relates to a drain device and more partaicularly to a waterpipe drain especially adapted for use in conjunction with outdoorfaucets so that the water in the vertical riser pipe extending to thefaucet as well as the Water in the faucet may be drained from a pointbelow the freezing level with the water being discharged into the groundat below freezing level.

An object of the present invention is to provide a water pipe drainincorporating an inverted receptacle forming means for discharging thedrained water into the ground surface.

A further object of the present invention is to provide a water pipedrain in accordance with the preceding object in which a control valvefor the Water pipe drain is operable and at the ground level.

Another important feature of the present invention is to provide a waterpipe drain which is easily assembled and constructed of readilyobtainable materials thus rendering the device extremely inexpensive tomanufacture.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view of the water pipe drain of the presentinvention with the soil and being broken away illustrating the detailsof the Water pipe drain;

FIGURE 2 is a vertical sectional view taken substantially upon a planepassing along section line 2-2 of FIGURE 1;

FIGURE 3 is a detailed sectional view taken substantially upon a planepassing along section line 33 of FIG- URE 2 illustrating the details ofconstruction of the drain valve;

FIGURE 4 is a vertical sectional view taken substantially upon a planepassing along section line 4--4 of FIGURE 1 illustrating the details ofconstruction of the inverted container; and

FIGURE 5 is an elevational view illustrating a modified form of theinvention.

Referring now specifically to the drawings, the numeral generallydesignates the water pipe drain assembly of the present invention whichincludes a water supply pipe 12 having any suitable pressure and of anydesired size which is normally used in water supply pipes of thisnature. The water supply 12 is buried in the ground 14 in such a mannerthat it would normally be below the freezing line in the particularlocality in which the device is installed.

The water supply pipe 12 is provided with a valve generally designatedby the numeral 16 and a T-fitting 1S and an end cap 20 with theT-fitting 18 being connected to a vertical riser or stand pipe 22 by twoL-couplings 24 with suitable nipples being provided between thesevarious couplings. The upper end of the stand pipe 22 is provided withan L-shaped coupling 26' having a valve 28 connected thereto which iscontrolled by a hand wheel 30 for discharging water through a faucet orspigot 32.

The valve 16 includes a housing 40 having two longitudinally opposedends connected to adjacent sections of the water supply pipe 12. Abranch line 42 is provided in perpendicular relation to the end portionsdesignated ice I by the numeral 44 which are in longitudinal opposition.Rotatable in the housing 40 is a valve core 46 having a T-shaped passage48 therein. The valve core 46 is connected with an operating handle 50extending vertically upwardly through a pipe 52 and terminating in anoffset handle portion 54 disposed above ground level. The upper end ofthe pipe 52 is sealed to the operating rod 50 by a tapered resilientstopper 56, thus sealing the rod 50 in relation to the tubular pipe 52thus preventing entry of water into this area. The pipe 52 as well asthe pipe 22 extends through a slab of concrete 58 which has the greatestthickness at the pipe 52 and then tapers towards the sides of theconcrete plate 58 for assuring proper drainage of water away from thepipes 52 and 22.

Extending outwardly from the branch portion 42 of the valve housing 40is an elongated generally inclined drain pipe 60 extending into aninverted receptacle 62 having downwardly and outwardly flared peripheralwall 64 which defines a cavity within the ground 14 which is disposedbelow the freezing line. The cavity is designated by the numeral 66 andhas a series of downwardly extending sockets or bores 68 therein forreceiving the water for more effective discharge of the Water into thesoil.

Referring specifically to FIGURE 5, there has been provided acylindrical casing 70 in encircling relation to the pipes 52' and 22'with the area within the cylindrical member 70 and below the concreteplatform 58 is hardly packed dry soil 72.

In operation, rotation of the handle 54 for purposes of shutting ofiflow of water from the supply line 12 will cause the valve plug or core46 to rotate to supply line 12. When doing this, the T-shaped passageway48 in the valve core 46 will effectively drain the water from the standpipe 22 as well as the remainder of the pipe on the discharge side ofthe valve core 46.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes Willreadily occur to those skilled in the "art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly, all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

1. In an outdoor valved faucet including an underground water supplyline disposed below the freezing level and a vertically extending standpipe connecting the supply line with the faucet, a combined cut-off anddrain valve disposed in the water supply line and including a valvehousing, said valve being operable from the ground surface forsimultaneously cutting olf the supply line and communicating the faucetand stand pipe with a drain branch line on said housing for drainingWater from the stand pipe and faucet when the faucet is opened, aleadoff pipe communicated with said fitting, and an inverted receptacledisposed in the ground with the bottom thereof below the supply pipewith the lead-off pipe communicated with the receptacle for dischargingthe drained water into the soil, said combination cut-off and drainvalve being provided with an elongated operating rod having a lateralhandle at the upper end above the ground surface, a tubular pipe memberenclosing said rod to a point above the ground surface and being sealedin relation to the valve housing, and a resilient seal in the upper endof the rod enclosing pipe with tthe seal being disposed in encirclingrelation to the operating rod for preventing entry of Water into the rodenclosing pipe for preventing freezing damage to the rod and pipe, and aconcrete slab receiving the stand pipe and rod enclosing pipe, said slabhaving a high portion flush with the upper end of the rod enclosing pipeand being inclined away from the rod enclosing pipe for drainage ofwater away from said pipe.

2. The combination of claim 1 together with a cylindrical memberenclosing the. stand pipe and rod enclosin-g pipe, saidcylindlicalmember; having a bottom for preventing entry of excesswaterinto this area for assuring' effective distribution of water fromdraining of the stand pipe and faucet.

3. The combination of claim 2 wherein said inverted receptacle isprovided with an outwardly flared wall and overlies a plurality ofdownwardly extending passageways formed in the ground for moreefiectively discharging water into the ground.
